ABSTRACT

A humanoid traffic control robot is provided, which is installed on all or some of the lanes of a road where maintenance work, subway construction, or an unexpected situation such as a traffic accident takes place and allows arm parts of a robot body thereof to freely implement desired arm operations and thus to more easily perform a variety of traffic control signal services.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a humanoid traffic control robot, which is installed on all or some of the lanes of a road where maintenance work, subway construction, or an unexpected situation such as a traffic accident takes place and allows arm parts of a robot body thereof to freely implement desired arm operations and thus to more easily perform a variety of traffic control signal services.

2. Description of the Prior Art

In general, when maintenance work, subway construction, or an unexpected situation such as a traffic accident takes place on a road, traffic control is performed on all or some of lanes of the road. In this case, a guide is deployed in front of the traffic control lanes, and controls traffic using flags or directing lamps.

As described above, if the guide performs the traffic control for a long time, he becomes exhausted. As a result, the guide cannot perform the traffic control, and furthermore is always exposed to the danger of a traffic accident. In adverse weather conditions such as rainy weather, the guide cannot smoothly perform traffic control.

To overcome this problem, a traffic control apparatus using a mannequin has recently been proposed, which converts rotational motion into linear reciprocating motion by means of operation of a crank mechanism connected to a reduction motor, so that the right arm of the mannequin performs traffic control while pivoting at a predetermined angle.

However, such a traffic control apparatus merely allows the arm to move up and down within a predetermined angle, i.e. cannot freely carry out the desired arm operation, so it cannot perform a variety of traffic control signal services.

SUMMARY OF THE INVENTION

Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an objective of the present invention is to provide a humanoid traffic control robot, which is installed on all or some of the lanes of a road where maintenance work, subway construction, or an unexpected situation such as a traffic accident takes place and allows arm parts of a robot body thereof to freely implement desired arm operations and thus to more easily perform a variety of traffic control signal services.

In order to achieve the above objective, according to the present invention, there is provided a humanoid traffic control robot, which comprises: a robot body; a guide-rod fixing unit that is provided on each of opposite sides of the robot body, and is rotated around an upper portion thereof at a predetermined angle with a guide rod fixed to a lower portion thereof; a rotating unit that is rotatably coupled with the upper portion of the guide-rod fixing unit at a lower portion thereof, and rotates the upper portion of the guide-rod fixing unit in a forward or backward direction to allow the lower portion of the guide-rod fixing unit to be vertically rotated at a predetermined angle; a positioning unit that is coupled with an upper portion of the rotating unit so as to be horizontally rotatable around its axis at a lower portion thereof, and allows the rotating unit to be fixed along with the guide-rod fixing unit after being horizontally rotated around its axis; a vertical angle adjusting unit that is coupled with an upper portion of the positioning unit on an outer surface thereof, allow the lower portion of the positioning unit to be vertically rotated around the upper portion of the positioning unit at a predetermined angle such that the positioning unit can be fixed along with the rotating unit and the guide-rod fixing unit after being vertically rotated at a predetermined angle; and a horizontal angle adjusting unit that is coupled to each of the opposite sides of the robot body so as to be horizontally rotatable around its axis with the vertical angle adjusting unit connected to a lower portion thereof, and allows the vertical angle adjusting unit to be fixed along with the positioning unit, the rotating unit and the guide-rod fixing unit after being horizontally rotated at a predetermined angle.

Here, the positioning unit may include: a horizontal plate that includes a vertical plate, an upper portion of which is coupled to the outer surface of the vertical angle adjusting unit, an upper surface thereof, a hollow holder member protruding upwardly from the upper surface thereof so as to be located adjacent to the vertical plate, and an insertion pin protruding from a lower surface thereof in a downward direction; a rotary plate that is horizontally installed on the upper portion of the rotating unit, is coupled to the lower portion of the horizontal plate so as to be horizontally rotatable around its axis, and includes insertion through-holes which are formed at equal intervals and into which the insertion pin of the horizontal plate is inserted and a hollow holder member protruding downwardly from a lower surface thereof; and a fixing member that includes: a fixing bolt that passes through the rotary plate and the horizontal plate, and is held in the holder member of the rotary plate and the holder member of the horizontal plate, and has a head formed at a lower end thereof and coming into contact with the lower surface of the rotary plate; a nut that is screwed to an upper end of the fixing bolt; and an elastic member that is vertically interposed between the nut and the upper surface of the horizontal plate, and is held in the holder member of the horizontal plate with a cylindrical body of the fixing bolt surrounded.

Further, the vertical angle adjusting unit may include: a vertical plate that is rotatably coupled with the upper portion of the positioning unit on the outer surface thereof, and includes insertion through-holes formed at equal intervals and an insertion pin inserted into one of the insertion through-holes and protruding from an upper inner surface of the positioning unit toward the insertion through-holes; and a fixing member that includes: a fixing bolt that passes through the upper portion of the positioning unit and the vertical plate in a horizontal direction, and rotatably couples the upper portion of the positioning unit to the outer surface of the vertical plate, and has a head formed at one end thereof and coming into contact with the upper outer surface of the positioning unit; a nut that is screwed to the other end of the fixing bolt; and an elastic member that is horizontally interposed between the nut and an inner surface of the vertical plate, and surrounds a cylindrical body of the fixing bolt.

Further, the robot body may include a mount, to which the horizontal angle adjusting unit is coupled so as to be horizontally rotatable around its axis, at each of opposite upper portions thereof. The horizontal angle adjusting unit may include: a rotary plate that is coupled to an upper surface of the mount so as to be rotatable around its axis in a horizontal direction, has an arcuate guide slit, and is connected with the vertical angle adjusting unit at a lower portion thereof; a first fixing member that is held in the guide slit of the rotary plate, vertically pass through the mount, and is positioned at an upper portion of the mount; and a second fixing member that vertically passes through the rotary plate and the mount so as to be located adjacent to the first fixing member, and rotatably couples the rotary plate to the upper surface of the mount.

Furthermore, the robot body may include a horizontal width adjusting unit that adjusts a horizontal width between the horizontal angle adjusting units, which are coupled to the opposite upper portions of the robot body so as to be horizontally rotatable around its axis at a predetermined angle. The horizontal width adjusting unit may include: a horizontal movable bar that is coupled to the horizontal angle adjusting unit so as to be opposite to the horizontal angle adjusting unit, is installed so as to be horizontally movable at each of the opposite upper portions of the robot body, and has a plurality of pairs of through-holes which are horizontally arranged at regular intervals; a guide pipe that is horizontally fixed to each of the opposite upper portions of the robot body with the horizontal movable bar housed therein, guides horizontal movement of the horizontal movable bar, and has a pair of through-holes corresponding to each pair of through-holes of the horizontal movable bar; and a fixing member that is inserted and fixed into the through-holes of the guide pipe and the through-holes of the horizontal movable bar that are aligned to each other and fixes the horizontal movable bar.

Further, the robot body may include: a base; a pair of vertical frames that are vertically installed on the base so as to allow a height to be adjusted and are each coupled to the horizontal angle adjusting unit so as to be horizontally rotatable around its axis at an upper portion thereof; a fixing plate that is horizontally installed on the upper portion of each vertical frame so as to be located between the vertical frames; and a chest part that is fixed to an upper surface of the fixing plate.

Also, each vertical frame of the robot body may include: a lower vertical frame that is vertically installed on the base and has a plurality of pairs of through-holes vertically arranged at regular intervals; an upper vertical frame that is vertically displaced with the lower vertical frame housed therein and has a pair of through-holes corresponding to each pair of through-holes of the lower vertical frame; and a fixing member that is inserted and fixed into the through-holes of the upper vertical frame and the through-holes of the lower vertical frame that are aligned to each other and fixes the upper vertical frame that has been vertically displaced.

Further, the humanoid traffic control robot may further include: a battery that supplies current to the rotating unit; a timer setting part that sets information about a time at which the rotating unit rotates the upper portion of the guide-rod fixing unit in a forward or backward direction; and a controller controls the battery to supply the current to the rotating unit according to a setting value of the timer setting part.

In addition, the humanoid traffic control robot may further include a current quantity adjuster that adjusts a quantity of current of the battery which is supplied to the rotating unit by the controller.

According to the present invention, the lower portion of the guide-rod fixing unit is vertically rotated at a predetermined angle, and the rotating unit is fixed along the guide-rod fixing unit by the positioning unit after being horizontally rotated around its axis. Further, the positioning unit is fixed along with the rotating unit and the guide-rod fixing unit by the vertical angle adjusting unit after being vertically rotated at a predetermined angle, and the vertical angle adjusting unit is fixed along with the positioning unit, the rotating unit, and the guide-rod fixing unit by the horizontal angle adjusting unit after being horizontally rotated at a predetermined angle. As a result, the guide-rod fixing unit, the rotating unit, the positioning unit, the vertical angle adjusting unit, and the horizontal angle adjusting unit, all of which form each arm part of the robot body, can freely implement the desired arm operation, and thus can more easily perform a variety of traffic control signal services on all or some of the lanes of a road where maintenance work, subway construction, or an unexpected situation such as a traffic accident takes place.

Further, the rotating unit can be more easily fixed along with the guide-rod fixing unit by the positioning unit having the horizontal plate, the rotary plate and the fixing member after being horizontally rotated around its axis. Due to the elastic member that is vertically interposed between the nut of the fixing member and the upper surface of the horizontal plate of the positioning unit, the rotating unit can be subjected to easier adjustment of the horizontally rotated position along with the guide-rod fixing unit without releasing the fixed state of the fixing member each time.

Further, the positioning unit can be more easily fixed along with the rotating unit and the guide-rod fixing unit by the vertical angle adjusting unit having the vertical plate and the fixing member after being vertically rotated at a predetermined angle. In particular, due to the elastic member that is horizontally interposed between the nut of the fixing member and the inner surface of the vertical plate of the vertical angle adjusting unit, the positioning unit can be more easily rotated in a vertical direction along with the rotating unit and the guide-rod fixing unit without releasing the fixed state of the fixing member each time.

Furthermore, the vertical angle adjusting unit can be more easily fixed along with the positioning unit, the rotating unit, and the guide-rod fixing unit by the horizontal angle adjusting unit having the rotary plate and the first and second fixing members after being horizontally rotated at a predetermined angle.

In addition, the horizontal width between the horizontal angle adjusting units can be more easily adjusted as needed by the horizontal width adjusting unit, which has the horizontal movable bar, the guide pipe, and the fixing member in order to improve easy storage and transportation of the robot body.

Further, the height of the vertical frames can also be more easily adjusted as needed, because the vertical frames of the robot body are vertically installed on the base so as to make its height adjustable in order to improve easy storage and transportation of the robot body.

In particular, since each vertical frame is made up of the lower vertical frame, the upper vertical frame vertically displaced with the lower vertical frame housed therein, and the fixing member fixing the upper vertical frame that has been vertically displaced, the height of the vertical frame can be more easily adjusted as needed.

Further, since the controller controls the battery to supply its current to the rotating unit according to a setting value of the timer setting part, unnecessary power consumption of the rotating unit can be more easily prevented.

In addition, the current quantity adjuster, which adjusts the current quantity of the battery which is supplied to the rotating unit, allows the rotating unit to rotate the upper portion of the guide-rod fixing unit in a forward or backward direction at a high or low speed, and allows the battery to reduce power consumption and be used for a longer time.

DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in greater detail to various exemplary embodiments of the invention with reference to the accompanying drawings. Of course, it will be understood that the present description is not intended to limit the invention to those exemplary embodiments. On the contrary, the invention is intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.

As shown in FIG. 1, a humanoid traffic control robot according to an exemplary embodiment of the present invention generally includes a robot body 10, a guide-rod fixing unit 30, a rotating unit 50, a positioning unit 70, a vertical angle adjusting unit 90, and a horizontal angle adjusting unit 100.

First, the robot body 10 may be installed on the ground including a road where maintenance work, subway construction, or an unexpected situation such as a traffic accident takes place.

Next, the guide-rod fixing unit 30 may be vertically provided on each of the opposite sides of the center of the robot body 10, as shown in FIG. 1.

FIG. 2 is a partially enlarged perspective view schematically showing vertical rotation of the guide-rod fixing unit 30 at a predetermined angle.

The guide-rod fixing unit 30 can be fitted with the grip 31 a of a guide rod 31 such as a flashing rod, which emits light under the control of a controller (not shown), at a lower portion thereof by a worker.

In this state, the lower portion of the guide-rod fixing unit 30 is vertically rotated around an upper portion of the guide-rod fixing unit 30 at a predetermined angle. Here, the guide-rod fixing unit 30 can be vertically rotated around its axis at a predetermined angle.

As shown in FIG. 2, the guide-rod fixing unit 30 generally includes a rotary member 310, a guide-rod fixture member 330, and a guide-rod anti-separation member 350.

The rotary member 310 may be vertically rotated forward or backward by the rotating unit 50 in the state where it is rotatably coupled to an outer surface of the rotating unit 50.

The guide-rod fixture member 330 may be vertically rotated forward or backward at a predetermined angle along with the rotary member 310 in the state where it is integrally formed with a lower portion of the rotary member 310 in a vertical direction.

The guide-rod fixture member 330 may have the cross-section of a “C” shape in which an outer side thereof is open so that the grip 31 a of the guide rod 31 can be more easily fitted into the guide-rod fixture member 330.

The guide-rod anti-separation member 350 may be made up of front guide-rod anti-separation members 351 and rear guide-rod anti-separation members 353.

The front guide-rod anti-separation members 351 may be vertically installed on a front lower end of the guide-rod fixture member 330 at predetermined intervals in the state where they horizontally extend from the front lower end of the guide-rod fixture member 330 in an outward direction.

The front guide-rod anti-separation members 351 are inclined at the front lower end of the guide-rod fixture member 330 toward an outer circumference of the grip 31 a of the guide rod 31 fitted in the guide-rod fixture member 330 in a front-to-rear direction, so that they can be closely fixed to the outer circumference of the grip 31 a of the guide rod 31.

The rear guide-rod anti-separation members 353 may be vertically installed on a rear lower end of the guide-rod fixture member 330 at predetermined intervals in the state where they horizontally extend from the rear lower end of the guide-rod fixture member 330 in an outward direction.

The front guide-rod anti-separation members 351 are inclined at the rear lower end of the guide-rod fixture member 330 toward an outer circumference of the grip 31 a of the guide rod 31 fitted in the guide-rod fixture member 330 in a rear-to-front direction, so that they can be closely fixed to the outer circumference of the grip 31 a of the guide rod 31.

Next, the upper portion of the guide-rod fixing unit 30 is rotatably coupled to the lower portion of the rotating unit 50.

As shown in FIG. 2, the rotating unit 50 rotates the upper portion of the guide-rod fixing unit 30 under the control of the controller (not shown) in a forward or backward direction so that the lower portion of the guide-rod fixing unit 30 can be vertically rotated at a predetermined angle.

The rotating unit 50 generally includes a rotary body 510, a driving motor 530, and a gearbox 550.

An upper portion of the rotary body 510 is coupled to a lower portion of the positioning unit 70 by a worker so that the rotary body 510 can be rotated around its axis in a horizontal direction.

The driving motor 530 is vertically installed in the rotary body 510. The driving motor 530 is provided with a drive shaft at a lower end thereof. The drive shaft of the driving motor 530 can be rotated under the control of the controller (not shown) in a forward or backward direction.

The gearbox 550 is vertically installed on a lower portion of the rotary body 510 in the state where it is rotatably coupled with the drive shaft of the driving motor 530.

The gearbox 550 is a box in which a pair of gears or a plurality of pairs of gears are housed. The gearbox 550 reduces a rotational speed of the drive shaft of the driving motor 530 or converts a rotational direction of the drive shaft of the driving motor 530. This is known technology, which can be easily understood and practiced by those skilled in the art to which the present invention belongs, and so detailed description thereof will be omitted.

The rotary member 310 of the guide-rod fixing unit 30 is rotatably coupled to the lower portion of the gearbox 550.

The rotary member 310 of the guide-rod fixing unit 30 receives a rotational force of the driving motor 530 via the gearbox 550, and is vertically rotated forward or backward as shown in FIG. 2.

Thus, the guide-rod fixture member 330, which is integrally installed on the lower portion of the rotary member 310 in a vertical direction and in which the grip 31 a of the guide rod 31 is fixedly fitted, is vertically rotated at a predetermined angle along with the guide rod 31.

Next, the upper portion of the rotary body 510 of the rotating unit 50 is coupled to a lower portion of the positioning unit 70 by a worker such that the rotary body 510 can be horizontally rotated around its axis.

FIG. 3 is a partially enlarged perspective view schematically showing the rotating unit 50 that is horizontally rotated around its axis along with the guide-rod fixing unit 30 and thereby is positioned. FIG. 4 is a partially enlarged cross-sectional view taken along line A-A of FIG. 3.

When a worker horizontally rotates the rotary body 510 of the rotating unit 50 around its axis, the guide-rod fixing unit 30 can be horizontally rotated around its axis along with the rotating unit 50 and thereby be positioned as shown in FIG. 3.

As shown in FIGS. 2 through 4, the positioning unit 70 generally includes a circular horizontal plate 710, a circular rotary plate 730, and a fixing member 750.

The horizontal plate 710 is provided with a vertical plate 711, which integrally extends upwardly from an upper surface thereof at a predetermined length, so as to be located out of the center thereof, i.e. so as to be located adjacent to the center thereof.

An upper portion of the vertical plate 711 is coupled to the outer surface of the vertical angle adjusting unit 90.

The horizontal plate 710 is provided with a hollow holder member 713 at the center of the upper surface thereof so as to be located adjacent to the vertical plate 711. The holder member 713 protrudes upwardly from the upper surface of the horizontal plate 710.

As shown in FIG. 4, the horizontal plate 710 is provided with an insertion pin 715 on a lower surface thereof which protrudes out of the center thereof in a downward direction.

The rotary plate 730 is integrally installed on the upper portion of the rotating unit 50 in a horizontal direction.

The rotary plate 730 is coupled below the horizontal plate 710 so as to be able to be rotated around its axis in a horizontal direction.

As shown in FIG. 4, the rotary plate 730 is provided with insertion through-holes 731, which are formed at equal intervals and into which the insertion pin 715 of the horizontal plate 710 is inserted.

The rotary plate 730 is provided with a hollow holder member 733 at the center of a lower surface thereof which protrudes downwardly from the lower surface thereof.

As shown in FIG. 4, the fixing member 750 generally includes a fixing bolt 751, a nut 753, and an elastic member 755.

The fixing bolt 751 passes through openings 732 and 712 formed in the centers of the rotary plate 730 and the horizontal plate 710 respectively, and is held in the holder member 733 of the rotary plate 730 and the holder member 713 of the horizontal plate 710.

The fixing bolt 751 has a head 751 a formed at a lower end thereof. The head 751 a comes into contact with the lower surface of the rotary plate 730.

The nut 753 is screwed to an upper end of the fixing bolt 751.

The elastic member 755 is vertically interposed between the nut 753 and the upper surface of the horizontal plate 710.

The elastic member 755 is held in the holder member 713 of the horizontal plate 710 with a cylindrical body of the fixing bolt 751 surrounded.

Since the elastic member 755 is held in the holder member 713 of the horizontal plate 710, the worker is safe from accidentally jamming a finger in the elastic member 755. The elastic member 755 may include a spring, but it is not limited thereto.

The worker can grasp the rotary body 510 of the rotating unit 59, and then move it in a downward direction.

At this time, as shown in a) of FIG. 4, the rotary plate 730 contacting the horizontal plate 710, and the fixing bolt 751 and the nut 753 move along the rotary body 510 in a downward direction, and simultaneously the elastic member 755 is contracted.

In this state, the worker horizontally rotates the rotary body 510 so that the rotary plate 730 can be horizontally rotated around its axis.

After the rotary plate 730 and the rotary body 510 are positioned by the horizontal rotation by the worker, the worker releases the rotary body 510, so that the contracted elastic member 755 is expanded, i.e. returns to its original shape.

Thus, the rotary plate 730 and the rotary body 510, which have been positioned by the horizontal rotation, move in an upward direction by means of an expansion force of the elastic member 755. At this time, as shown in b) of FIG. 4, the rotary plate 730, which has been positioned by the horizontal rotation, allows its upper surface to come into contact with the lower surface of the horizontal plate 710.

The insertion pin 715 of the horizontal plate 710 is inserted into one of the insertion holes 731 formed in the rotary plate 730, which has been positioned by the horizontal rotation, at equal intervals, thereby immobilizes the rotary plate 730 and the rotary body 510, which have been positioned by the horizontal rotation.

Meanwhile, the fixing member 750 may be made up of the fixing bolt 751, whose head 751 a is formed at a lower end thereof and comes into contact with the lower surface of the rotary plate 730, and the nut 753 that is screwed on the upper end of the fixing bolt 751 and is in contact with the upper surface of the horizontal plate 710. In this case, the worker has trouble to release the immobilized state of the fixing member 750 made up of the fixing bolt 751 and the nut 753 each time in order to horizontally rotate the rotary plate 730 and the rotary body 510.

For this reason, to resolve the problem of releasing the immobilized state of the fixing member 750 each time, the fixing member 750 is preferably made up of the fixing bolt 751, the nut 753, and the elastic member 755.

The positioning unit 70, which includes the horizontal plate 710, the rotary plate 730, and the fixing member 750, allows the rotating unit 50 to be more easily immobilized after the rotating unit 50 is horizontally rotated around its axis along with the guide-rod fixing unit 30. In particular, the elastic member 755 of the fixing member 750 of the positioning unit 70 allows the horizontal rotation of the rotating unit 50 to be more easily adjusted along with the guide-rod fixing unit 30 without the trouble to release the immobilized state of the fixing member 750 each time.

FIG. 5 is a partially enlarged perspective view schematically showing the positioning unit 70 that is vertically rotated around its axis at a predetermined angle along with the rotating unit 50 and the guide-rod fixing unit 30. FIG. 6 is a schematic right side view showing the positioning unit 70 that is vertically rotated around its axis at a predetermined angle along with the rotating unit 50 and the guide-rod fixing unit 30. FIG. 7 is a partially enlarged cross-sectional view taken along line B-B of FIG. 6.

An upper portion of the positioning unit 70 is rotatably coupled to the vertical angle adjusting unit 90.

A lower portion of the positioning unit 70 is vertically rotated around the upper portion of the positioning unit 70 at a predetermined angle by a worker.

When the lower portion of the positioning unit 70 is vertically rotated at a predetermined by the worker, the rotary body 510 and the guide-rod fixing unit 30 are vertically rotated at a predetermined angle along with the positioning unit 70 as shown in FIGS. 5 and 6.

The vertical angle adjusting unit 90 immobilizes the positioning unit 70 that is vertically rotated at a predetermined angle along with the rotary body 510 and the guide-rod fixing unit 30.

As shown in FIGS. 2, 3, 5, 6 and 7, the vertical angle adjusting unit 90 generally includes a circular vertical plate 910 and a fixing member 930.

The vertical plate 910 is rotatably coupled with the upper portion of the vertical plate 711, which integrally extends upwardly from the upper surface of the horizontal plate 710 of the positioning unit 70 in an off-centered state, at the center thereof.

The vertical plate 910 may be provided with insertion through-holes 911 at equal intervals.

As shown in a) and b) of FIG. 7, an insertion pin 714, which horizontally protrudes from the upper portion of the vertical plate 711 of the positioning unit 70 toward the insertion through-holes 911, is inserted into one of the insertion through-holes 911 of the vertical plate 910.

The fixing member 930 includes a fixing bolt 931, a nut 933, and an elastic member 935.

The fixing bolt 931 passes through the center of the vertical plate 910 and the upper portion of the vertical plate 711 of the positioning unit 70, and then rotatably couples the vertical plate 910 with the upper portion of the vertical plate 711 of the positioning unit 70.

The fixing bolt 931 has a head 931 a formed at one end thereof. The head 931 a comes into contact with the upper outer surface of the vertical plate 711 of the positioning unit 70.

The nut 933 is screwed to the other end of the fixing bolt 931.

The elastic member 935 is horizontally interposed between the nut 933 and an inner surface of the vertical plate 910, and surrounds a cylindrical body of the fixing bolt 931.

The elastic member 935 may include a spring, but it is not limited thereto.

The worker can grasp the vertical plate 711 of the positioning unit 70, and then move it away from the vertical plate 910 of the vertical angle adjusting unit 90, as shown in a) of FIG. 7.

At this time, the fixing bolt 931 and the nut 933 moves toward the vertical plate 711 of the positioning unit 70, and simultaneously the elastic member 935 is contracted.

In this state, as shown in FIG. 5, the worker vertically rotates the lower portion of the positioning unit 70 around the upper portion of the positioning unit 70 at a predetermined angle.

When the lower portion of the positioning unit 70 is vertically rotated at a predetermined angle by the worker, the rotating unit 50 and the guide-rod fixing unit 30 are vertically rotated along with the positioning unit 70 at a predetermined angle.

After the positioning unit 70 is vertically rotated along with the rotating unit 50 and the guide-rod fixing unit 30 at a predetermined angle, the worker releases the vertical plate 711 of the positioning unit 70. Thereby, the contracted elastic member 935 returns to its original shape.

When the elastic member 935 returns to its original shape, the vertical plate 711 of the positioning unit 70, which is vertically rotated along with the rotating unit 50 and the guide-rod fixing unit 30, moves toward the vertical plate 910 as shown in b) of FIG. 7, and thus comes into contact with the outer surface of the vertical plate 910 of the vertical angle adjusting unit 90.

Here, the insertion pin 714, which protrudes inwardly from the upper portion of the vertical plate 711 of the positioning unit 70 in a horizontal direction, is inserted into one of the insertion through-holes 911 formed in the vertical plate 910 of the vertical angle adjusting unit 90 at equal intervals, and thereby immobilizes the positioning unit 70 that has been vertically rotated along with the rotating unit 50 and the guide-rod fixing unit 30 at a predetermined angle.

Meanwhile, the fixing member 930 may be made up of the fixing bolt 931, whose head 931 a is formed at one end thereof and comes into contact with the upper outer surface of the vertical plate 711 of the positioning unit 70, and the nut 933 that is screwed on the other end of the fixing bolt 931 and is in contact with the inner surface of the vertical plate 910 of the vertical angle adjusting unit 90. In this case, the worker has trouble to release the immobilized state of the fixing member 930 made up of the fixing bolt 931 and the nut 933 each time in order to vertically rotate the positioning unit 70 along with the rotating unit 50 and the guide-rod fixing unit 30 at a predetermined angle.

For this reason, to remove the trouble to release the immobilized state of the fixing member 930 each time, the fixing member 930 is preferably made up of the fixing bolt 931, the nut 933, and the elastic member 935.

Furthermore, to prevent the worker from accidentally jamming a finger in the elastic member 935, as shown in a) and b) of FIG. 7, the vertical plate 910 of the vertical angle adjusting unit 90 is provided with a holder member 913 at the center of the inner surface thereof in which the other end of the fixing bolt 931 of the fixing member 930 and the elastic member 935 surrounding a cylindrical body of the fixing bolt 931 of the fixing member 930 are held and which horizontally protrudes inwardly from the vertical plate 910 of the vertical angle adjusting unit 90.

The vertical angle adjusting unit 90, which includes the vertical plate 910 and the fixing member 950, allows the positioning unit 70 to be more easily immobilized after the positioning unit 70 is vertically rotated along with the rotating unit 50 and the guide-rod fixing unit 30 at a predetermined angle. In particular, the elastic member 935 of the fixing member 930 of the vertical angle adjusting unit 90 allows positioning unit 70 to be more easily rotated along with the rotating unit 50 and the guide-rod fixing unit 30 without the trouble to release the immobilized state of the fixing member 930 each time.

FIG. 8 is a partially enlarged perspective view schematically showing the vertical angle adjusting unit 90 that is horizontally rotated at a predetermined angle along with the positioning unit 70, the rotating unit 50 and the guide-rod fixing unit 30. FIG. 9 is a schematic front view showing the vertical angle adjusting unit 90 that is horizontally rotated at a predetermined angle along with the positioning unit 70, the rotating unit 50 and the guide-rod fixing unit 30 and the positioning unit 70 that is vertically rotated around its axis at a predetermined angle along with the rotating unit 50 and the guide-rod fixing unit 30. FIG. 10 is a partially enlarged cross-sectional view taken along line C-C of FIG. 8.

As shown in FIGS. 2, 3, 5 and 8, the vertical angle adjusting unit 90 is connected to a lower portion of the horizontal angle adjusting unit 100.

The horizontal angle adjusting unit 100 is coupled on each of the opposite sides of the robot body 10 so as to be horizontally rotated around its axis at a predetermined angle by a worker, so that the vertical angle adjusting unit 90 can be horizontally rotated and immobilized at a predetermined angle along with the positioning unit 70, the rotating unit 50 and the guide-rod fixing unit 30.

In detail, as shown in FIGS. 8 and 9, the robot body 10 is provided with an “L” shaped mount 120 at each of the opposite upper portions (i.e. shoulder portions) thereof to which the horizontal angle adjusting unit 100 is mounted so as to be rotatable around its axis in a horizontal direction.

The mount 120 includes a vertical plate 122, which is integrally installed on the robot body 10, and a horizontal plate 124, which integrally extends outwardly from an upper portion of the vertical plate 122 in a horizontal outward direction of the robot body 10.

As shown in FIGS. 2, 3, 5, 8 and 10, the horizontal angle adjusting unit 100 generally includes a circular rotary plate 110, a first fixing member 130, and a second fixing member 150.

The rotary plate 110 is coupled to an upper surface of the horizontal plate 124 of the mount 120 so as to be rotatable around its axis in a horizontal direction.

The rotary plate 110 is provided with an arcuate guide slit 111, which is located adjacent to the center of the rotary plate 110.

The vertical plate 910 of the vertical angle adjusting unit 90 is integrally connected to the rotary plate 110.

In detail, the vertical plate 910 of the vertical angle adjusting unit 90 and the rotary plate 110 are integrally connected with a connecting plate 112 (FIGS. 2, 3, 5 and 8) between part of the circumference of the rotary plate 110 and part of the circumference of the vertical plate 910 of the vertical angle adjusting unit 90. Here, the connecting plate 112 is located in a vertical direction.

As shown in FIG. 10, the first fixing member 130 is positioned so as to be held in the guide slit 111 of the rotary plate 110, and to vertically pass through a through-hole 125 formed in one end of the horizontal plate 124 that is integrally formed at an upper portion of the vertical plate 122 of the mount 120.

The first fixing member 130 is made up of a wing bolt 131 and a nut 133.

The wing bolt 131 is fitted into the guide slit 111 of the rotary plate 110, and then passes through a through-hole 125 of the horizontal plate 124 of the mount 120 in a vertical direction.

The nut 133 is screwed to a lower end of the wind bolt 131, and is in contact with the lower surface of the horizontal plate 124 of the mount 120.

The second fixing member 150 vertically passes through the centers of the rotary plate 110 and the horizontal plate 124 of the mount 120 so as to be located adjacent to the wing bolt 131 of the first fixing member 130, and then rotatably couples the rotary plate 110 to the upper surface of the horizontal plate 124 of the mount 120.

The second fixing member 150 is made up of a fixing bolt 151 and a nut 153.

The fixing bolt 151 passes through a through-hole 113 formed in the center of the rotary plate 110 and a through-hole 126 formed in the other end of the horizontal plate 124 of the mount 120 in a vertical direction.

The fixing bolt 151 has a head 151 a formed at an upper end thereof. The head 151 a of the fixing bolt 151 is in contact with the upper surface of the rotary plate 110.

The nut 153 is screwed to a lower end of the fixing bolt 151.

The worker turns the first and second fixing members 130 and 150 in a reverse direction so that the first and second fixing members 130 and 150 can be unfixed, and then horizontally rotates the rotary plate 110 of the horizontal angle adjusting unit 100 around its axis as shown in FIG. 8.

When the rotary plate 110 of the horizontal angle adjusting unit 100 is horizontally rotated around its axis by the worker, the vertical angle adjusting unit 90, the positioning unit 70, the rotating unit 50, and the guide-rod fixing unit 30 can be horizontally rotated at a predetermined angle, as shown in FIG. 8.

After the rotary plate 110 of the horizontal angle adjusting unit 100 is horizontally rotated around its axis, the unfixed first and second fixing members 130 and 150 can be fixed. To this end, the worker turns the first and second fixing members 130 and 150 in a forward direction, and then firmly fixes the rotary plate 110 of the horizontal angle adjusting unit 100 that has been rotated in a horizontal direction.

In this state, as shown in FIG. 9, the positioning unit 70, the rotating unit 50, and the guide-rod fixing unit 30 are also fixed after being vertically rotated at a predetermined angle.

Meanwhile, to avoid the problem of releasing the fixed state of the second fixing member 150 each time, although not shown in the figures, an elastic member such as a spring may be interposed between the nut 153 of the second fixing member 150 and the lower surface of the horizontal plate 124 of the mount 120 so as to surround a cylindrical body of the fixing bolt 151 of the second fixing member 150.

Further, although not shown in the figures, to prevent the worker from accidentally jamming a finger in the elastic member interposed between the nut 153 of the second fixing member 150 and the lower surface of the horizontal plate 124 of the mount 120, the horizontal plate 124 of the mount 120 may be provided with a holder member, on the lower surface thereof, in which the elastic member surrounding the cylindrical body of the fixing bolt 151 of the second fixing member 150 is held, and which protrudes downwardly from the horizontal plate 124 of the mount 120.

As shown in FIG. 8, the vertical angle adjusting unit 90 can be more easily fixed along with the positioning unit 70, the rotating unit 50, and the guide-rod fixing unit 30 by the horizontal angle adjusting unit 100 having the rotary plate 110 and the first and second fixing members 130 and 150 after being horizontally rotated at a predetermined angle.

Next, as shown in FIG. 9, the horizontal angle adjusting unit 100, which is coupled to each of the opposite upper portions of the robot body 10 so as to be horizontally rotatable around its axis at a predetermined angle, is connected to a horizontal width adjusting unit 140 that adjusts a horizontal width W between the horizontal angle adjusting units 100.

The horizontal width adjusting unit 140 includes a horizontal movable bar 141, a guide pipe 143, and a fixing member 145.

The horizontal movable bar 141 is coupled to the horizontal angle adjusting unit 100 so as to be opposite to the horizontal angle adjusting unit 100 such that it can be horizontally moved at each of the opposite upper portions of the robot body 10 by a worker.

The horizontal movable bar 141 is provided with a plurality of through-holes 142 in front and rear surfaces thereof which are horizontally arranged at regular intervals.

The horizontal movable bar 141 is integrally coupled to the mount 120, which is coupled with the horizontal angle adjusting unit 100, at one end thereof.

The guide pipe 143 is horizontally fixed to each of the opposite upper portions of the robot body 10 with the horizontal movable bar 141 housed therein so that it can guide horizontal movement of the horizontal movable bar 141. Here, the guide pipes 143 fixed to the opposite upper portions of the robot body 10 are spaced apart from each other with a predetermined width.

The guide pipe 143 is provided with a pair of through-holes 144 in respective front and rear surface thereof which correspond to each pair of through-holes 142 of the horizontal movable bar 141.

The fixing member 145 may be implemented as a fixing axle, a fixing pin, or the like. The fixing member 145 is inserted and fixed into the through-holes 144 of the guide pipe 143 and the through-holes 142 of the horizontal movable bar 141 that are aligned to each other, so that it can fix the horizontal movable bar 141.

The horizontal width adjusting unit 140, which has the horizontal movable bar 141, the guide pipe 143, and the fixing member 145, allows the horizontal width W between the horizontal angle adjusting units 100 to be more easily adjusted as needed, and can greatly improve easy storage and transportation of the robot body 10.

Next, as shown in FIG. 9, the robot body 10 generally includes a base 11, a pair of vertical frames 13, a fixing plate 15, and a chest part 17.

The base 11 is firmly fixed to the ground including a road where maintenance work, subway construction, or an unexpected situation such as a traffic accident takes place by bolt anchorage.

The vertical frames 13 are vertically installed on the base 11 with a predetermined width such that their height can be adjusted by a worker.

As shown in FIGS. 6 and 9, each vertical frame 13 is provided with a fixing pipe 134 at an upper portion thereof which extends at a predetermined length in a horizontal direction.

A lower surface of the fixing pipe 134 is welded to an upper surface of the guide pipe 143 of the horizontal width adjusting unit 140.

Here, since the mount 120 coupled with the horizontal angle adjusting unit 100 is integrally coupled to one end of the horizontal movable bar 141 housed in the guide pipe 143, the horizontal angle adjusting unit 100 can be installed on the upper portion of each vertical frame 13 so as to be horizontally rotatable around its axis.

The fixing plate 15 is horizontally installed on the upper portion of each vertical frame 13 so as to be located between the vertical frames 13.

The chest part 17 is integrally welded to an upper surface of the fixing plate 15. Alternatively, as shown in FIG. 6, the chest part 17 may be hinged to a rear end of the fixing plate 15 on a rear side thereof such that, if necessary, a front side thereof can be pivoted by a worker.

A head 101 of the robot body 10 is located at an upper portion of the chest part 17.

Since the vertical frames 13 of the robot body 10 are vertically installed on the base 11 such that their height can be adjusted, the height of each frame 13 can also be easily adjusted as needed, and thus the storage and transportation of the robot body 10 can be made easier.

Next, as shown in FIG. 9, each vertical frame 13 generally includes a lower vertical frame 13 a, an upper vertical frame 13 b, and a fixing member 13 c.

The lower vertical frame 13 a is provided with a plurality of through-holes 131 a (FIG. 9) in front and rear surface thereof which are vertically arranged at regular intervals.

The lower vertical frame 13 a is housed in the upper vertical frame 13 b. In this state, the upper vertical frame 13 b can be vertically displaced by a worker.

The upper vertical frame 13 b is provided with a pair of through-holes 131 b in respective front and rear surfaces of a lower end thereof which correspond to each pair of through-holes 131 a of the lower vertical frame 13 a.

The fixing member 13 c (FIG. 9) may be implemented as a fixing axle, a fixing pin, or the like. The fixing member 13 c is inserted and fixed into the through-holes 131 b of the upper vertical frame 13 b and the through-holes 131 a of the lower vertical frame 13 a that are aligned to each other, so that it can fix the upper vertical frame 13 b that has been vertically displaced.

Since each vertical frame 13 is constituted of the lower vertical frame 13 a, the upper vertical frame 13 b vertically displaced with the lower vertical frame 13 a housed therein, and the fixing member 13 c fixing the upper vertical frame 13 b that has been vertically displaced, a height of the vertical frame 13 can be more easily adjusted as needed.

Next, as shown in FIG. 9, a control box 136 having, for instance, a quadrilateral shape, is installed between the upper vertical frames 13 b of the vertical frames 13 at a predetermined height, and has a battery (not shown), a timer setting part (not shown), and the controller (not shown) housed therein.

The battery (not shown) is electrically connected with the driving motor 530 of the rotating unit 50 by a cable, and supplies current to the driving motor 530 of the rotating unit 50 under the control of the controller (not shown).

The timer setting part (not shown) is installed on the controller (not shown) in a push button type or a dial button type.

The timer setting part (not shown) is set with information about a time at which the driving motor 530 of the rotating unit 50 rotates the upper portion of the guide-rod fixing unit 30 in a forward or backward direction.

The information about the time at which the driving motor 530 of the rotating unit 50 rotates the upper portion of the guide-rod fixing unit 30 in a forward or backward direction and which is set for the timer setting part (not shown) may be a forward or backward rotation time or a backward or backward rotation time interval.

For example, it is assumed that the information about the time at which the driving motor 530 of the rotating unit 50 rotates the upper portion of the guide-rod fixing unit 30 in a forward or backward direction is the forward or backward rotation time, and that the forward or backward rotation time is 1 p.m., 3 p.m., 4 p.m. and 7 p.m.

The controller (not shown) controls the battery (not shown) to allow its current to be supplied to the driving motor 530 of the rotating unit 50 at 1 p.m., 3 p.m., 4 p.m. and 7

p.m. such that the upper portion of the guide-rod fixing unit 30 can be rotated in a forward or backward direction at 1 p.m., 3 p.m., 4 p.m. and 7 p.m.

Further, it is assumed that the information about the time at which the driving motor 530 of the rotating unit 50 rotates the upper portion of the guide-rod fixing unit 30 in a forward or backward direction is the forward or backward rotation time interval, and that the forward or backward rotation time interval is 30 minutes.

The controller (not shown) controls the battery (not shown) to allow its current to be supplied to the driving motor 530 of the rotating unit 50 at intervals of 30 minutes such that the upper portion of the guide-rod fixing unit 30 can be rotated in a forward or backward direction at intervals of 30 minutes.

Since the controller (not shown) controls the battery (not shown) to supply its current to the rotating unit 50 according to a setting value of the timer setting part (not shown), unnecessary power consumption of the rotating unit 50 can be more easily prevented.

Next, a current quantity adjuster (not shown) that adjusts a quantity of current of the battery 20→(not shown) which is supplied to the driving motor 530 of the rotating unit 50 under the control of the controller (not shown) is provided.

The current quantity adjuster (not shown) is installed on the controller (not shown) in a push button type or a dial button type.

When a worker operates the current quantity adjuster (not shown) in a “high” state to allow a large quantity of current to be supplied from the battery 20→(not shown) to the driving motor 530 of the rotating unit 50, the driving motor 530 of the rotating unit 50 rotates the upper portion of the guide-rod fixing unit 30 in a forward or backward direction at a high speed under the control of the controller (not shown).

When a worker operates the current quantity adjuster (not shown) in a “low” state to allow a small quantity of current to be supplied from the battery 20→(not shown) to the driving motor 530 of the rotating unit 50, the driving motor 530 of the rotating unit 50 rotates the upper portion of the guide-rod fixing unit 30 in a forward or backward direction at a low speed under the control of the controller (not shown).

The current quantity adjuster (not shown), which adjusts the current quantity of the battery (not shown) which is supplied to the rotating unit 50, allows the rotating unit 50 to rotate the upper portion of the guide-rod fixing unit 30 in a forward or backward direction at a high or low speed, and allows the battery (not shown) to reduce power consumption and be used for a longer time.

FIG. 11 is a partially enlarged front view schematically showing the state where the positioning unit 70, the vertical angle adjusting unit 90, and the horizontal angle adjusting unit 100 are rotatably coupled with respective driving motors.

As shown in FIG. 11, the positioning unit 70, the vertical angle adjusting unit 90, and the horizontal angle adjusting unit 100 are rotatably coupled with first, second and third driving motors 20, 40 and 60, respectively.

The first driving motor 20 is vertically fixed to the upper surface of the horizontal plate 710 of the positioning unit 70.

A drive shaft of the first driving motor 20, which is located at a lower end thereof, passes through the center of the horizontal plate 710 of the positioning unit 70, and is integrally coupled with the rotary plate 730 of the positioning unit 70.

The drive shaft of the first driving motor 20 is rotated in a forward or backward direction under the control of the controller (not shown), thereby automatically rotating the rotary plate 730 of the positioning unit 70 in a forward or backward direction.

The second driving motor 40 is horizontally fixed to the inner surface of the vertical plate 910 of the vertical angle adjusting unit 90.

A drive shaft of the second driving motor 40, which is located at one end thereof, passes through the center of the vertical plate 910 of the vertical angle adjusting unit 90, and is integrally coupled with the upper portion of the vertical plate 711 of the positioning unit 70.

The drive shaft of the second driving motor 40 is rotated in a forward or backward direction under the control of the controller (not shown), thereby automatically rotating the upper portion of the vertical plate 711 of the positioning unit 70 in a forward or backward direction.

The third driving motor 60 is vertically fixed to the lower surface of the horizontal plate 124 of the mount 120.

A drive shaft of the third driving motor 60, which is located at an upper end thereof, passes through the center of the horizontal plate 124 of the mount 120, and is integrally coupled with the rotary plate 110 of the horizontal angle adjusting unit 100.

The drive shaft of the third driving motor 60 is rotated in a forward or backward direction under the control of the controller (not shown), thereby automatically rotating the rotary plate 110 of the horizontal angle adjusting unit 100 in a forward or backward direction.

FIG. 12 is a front view schematically showing the state where right and left arm parts of the robot body 10 perform different operations.

As shown in FIG. 12, the guide-rod fixing unit 30, the rotating unit 50, the positioning unit 70, the vertical angle adjusting unit 90, and the horizontal angle adjusting unit 100 are not exposed to the outside by clothes including working clothes 5 put on the robot body 10.

Right and left arm parts of the robot body 10, which are installed on the opposite upper sides of the robot body 10 respectively by means of the guide-rod fixing unit 30, the rotating unit 50, the positioning unit 70, the vertical angle adjusting unit 90, and the horizontal angle adjusting unit 100, perform different operations, as shown in FIG. 12.

According to the present invention as described above, the guide-rod fixing unit 30, the rotating unit 50, the positioning unit 70, the vertical angle adjusting unit 90, and the horizontal angle adjusting unit 100, all of which form the arm parts of the robot body 10, can freely implement the desired arm operation, and thus can more easily perform a variety of traffic control signal services on all or some of the lanes of a road where maintenance work, subway construction, or an unexpected situation such as a traffic accident takes place.
